Association between radiography-based subchondral bone structure and MRI-based cartilage composition in postmenopausal women with mild osteoarthritis
2016
Summary Objective Our aim was to investigate the relation between radiograph-based subchondral bone structure and cartilage composition assessed with delayed gadolinium enhanced magnetic resonance imaging of cartilage (dGEMRIC) and T 2 relaxation time. Design Ninety-three postmenopausal women (Kellgren–Lawrence grade 0: n = 13, 1: n = 26, 2: n = 54) were included. Radiograph-based bone structure was assessed using entropy of the Laplacian-based image ( E Lap ) and local binary patterns ( E LBP ), homogeneity indices of the local angles (HI Angles,mean , HI Angles,Perp , HI Angles,Paral ), and horizontal (FD Hor ) and vertical fractal dimensions (FD Ver ). Mean dGEMRIC index and T 2 relax…
Cation binding resorcinarene bis-crowns: the effect of lower rim alkyl chain length on crystal packing and solid lipid nanoparticles
2012
A group of seven resorcinarene bis-crown ethers (CNBC5) with two polyether bridges at the upper rim and either propyl, butyl, pentyl, heptyl, nonyl, decyl or undecyl groups at the lower rim were synthesized and their binding properties with Cs+ were investigated by NMR titration. The bis-crowns form 1:2 complexes with Cs+ with binding constants of logK 4–5. Crystal structures of bis-crowns and their Cs+ and K+ complexes were studied and different packing motifs were found depending on the alkyl chain length. Short ethyl, propyl and butyl alkyl chains gave a layer or pillar packing where the polar and non-polar regions cannot be distinguished, whereas longer pentyl and decyl chains formed bi…
Production of Cultural Policy in Russia: Authority and Intellectual Leadership
2020
The paper discusses different frameworks of knowledge production within the discourses and practices of Russian cultural policy. Russian cultural policy as an administrative sector has been developed in line with two distinctive governmental regimes, more precisely during the period of liberal decentralisation of the 1990s and the conservative centralisation from 2011 up until today. The study focuses on the main changes that have occurred in the framework of policy design and participation in policy-making. An attempt is made to combine Foucauldian analytical frameworks of power and discourse with a Gramscian hegemonic approach to political studies that was mainly advocated by the Essex sc…
Theoretical study on travelling web dynamics and instability under non-homogeneous tension
2013
Problems of dynamics and stability of a moving web, travelling between two rollers at a constant velocity, are studied using analytical approaches. Transverse vibrations of the web are described by a partial differential equation that includes the centrifugal force, in-plane tension, elastic reaction and nonstationary inertial terms. The model of a thin elastic plate subjected to bending and non-homogeneous tension is used to describe the bending moment and the distribution of membrane forces. The stability of the plate is investigated with the help of studies of small out-of-plane vibrations. The influence of linearly distributed in-plane tension on the characteristics of the web vibration…
Endringskapasitet – en nøkkel for å lykkes med gevinstrealisering i spesialisthelsetjenesten? : En studie av hvordan mellomledere opplever at endring…
2018
Masteroppgave i helse- og sosialinformatikk HSI500 - Universitetet i Agder 2018 Background: If an organisation is to reap the potential benefits of new technology, it must modify its work processes. However, the specialist health service appears to be experiencing significant challenges because it is constantly under pressure to change and improve its efficiency. This can weaken its capacity for change and, at worst, lead to long-term reductions in productivity and efficiency. Purpose: The purpose of this study is to examine how middle managers in the specialist health service feel they can influence developments in change capacity. The aim is to contribute to an awareness of the importance…
Production of Λ and KS0 in jets in p–Pb collisions at √sNN = 5.02 TeV and pp collisions at √s = 7 TeV
2022
The production of Λ baryons and KS0 mesons (V0 particles) was measured in p–Pb collisions at √sNN=5.02 TeV and pp collisions at √s=7 TeV with ALICE at the LHC. The production of these strange particles is studied separately for particles associated with hard scatterings and the underlying event to shed light on the baryon-to-meson ratio enhancement observed at intermediate transverse momentum (pT) in high multiplicity pp and p–Pb collisions. Hard scatterings are selected on an event-by-event basis with jets reconstructed with the anti-kT algorithm using charged particles. The production of strange particles associated with jets pT,jetch>10 and pT,jetch>20 GeV/c in p–Pb collisions, and with …
Rap-imago rap-artisti Cheekin lyriikoissa
2014
Rap-musiikki on noussut muutaman viimeksi kuluneen vuoden aikana hyvin suosituksi Suomessa. Yksi suosituimmista ja tunnetuimmista rap-artisteista on artistinimeä Cheek käyttävä Jare Tiihonen. Cheek on julkaissut musiikkia yli kymmenen vuoden ajan ja hänen tuotantonsa on pääosin suomenkielistä. Cheekin tekstejä on jonkin verran tarkasteltu kielitieteellisissä tutkimuksissa, muttei imagonrakentamisen näkökulmasta. Yleisesti ottaen suomirapia on tutkittu toistaiseksi vähän. Tutkimuksessani tarkastelin Cheekin lyriikoissaan rakentamaa imagoa. Tutkimuskysymysteni pohjalta selvitin, minkälaisin kielellisin keinoin Cheek rakentaa imagoaan, minkälainen tämä rakentuva imago on ja kuinka kielen keino…
Theory for polaritonic quantum tunneling
2022
I investigate the tunneling decay rate of a polaritonic system formed by a strong coupling between a vacuum cavity mode and $N$ metastable systems. Using a simple model potential, I find the instanton solutions controlling the low-temperature tunneling rate. The resulting rate modification due to the cavity is proportional to the mean of the second power of the light-matter coupling. No collective effect that would enhance the rates by a factor of $\sqrt{N}$ is present, which is in line with the results in the thermal activation regime.
Geometry of Degeneracy in Potential and Density Space
2022
In a previous work [J. Chem. Phys. 155, 244111 (2021)], we found counterexamples to the fundamental Hohenberg-Kohn theorem from density-functional theory in finite-lattice systems represented by graphs. Here, we demonstrate that this only occurs at very peculiar and rare densities, those where density sets arising from degenerate ground states, called degeneracy regions, touch each other or the boundary of the whole density domain. Degeneracy regions are shown to generally be in the shape of the convex hull of an algebraic variety, even in the continuum setting. The geometry arising between density regions and the potentials that create them is analyzed and explained with examples that, amo…
Density-Functional Theory on Graphs
2021
The principles of density-functional theory are studied for finite lattice systems represented by graphs. Surprisingly, the fundamental Hohenberg–Kohn theorem is found void, in general, while many insights into the topological structure of the density-potential mapping can be won. We give precise conditions for a ground state to be uniquely v-representable and are able to prove that this property holds for almost all densities. A set of examples illustrates the theory and demonstrates the non-convexity of the pure-state constrained-search functional. peerReviewed
